Nishimta
In Mandaeism, the nishimta or nishma is the human soul. It is can also be considered as equivalent to the "psyche" or "ego". It is distinct from ruha, as well as from mana. In Mandaeism, humans are considered to be made up of the physical body, soul, and spirit.
In the afterlife
When a Mandaean person dies, priests perform elaborate death rituals or death masses called masiqta in order to help guide the soul towards the World of Light. In order to pass from Tibil to the World of Light, the soul must go through multiple maṭarta before finally being reunited with the dmuta, the soul's heavenly counterpart.A successful masiqta merges the incarnate soul and spirit from the Earth into a new merged entity in the World of Light called the ʿuṣṭuna. The ʿuṣṭuna can then reunite with its heavenly, non-incarnate counterpart, the dmuta, in the World of Light, where it will reside in the world of ideal counterparts.
